I want to make walls by planting natural trees like Hicksii Yew and Green Velvet Boxwood. What are your advices? I would like to invite you at my home to discuss these or you may send me all the information regarding the above mentioned project. What are the best trees to grow in MN for fencings? How does the weather affects them? What months to start growing them? How much does it cost or how expensive are they? Thank you all, I really appreciate your assistance and your services too. Thanks Abdi at White Bear Lake MN
